Player housing/alt grinding:
What if, we had a place where all of our alts kind of milled about like NPCs did in our garrison? And what if they worked together in such a way that, say, I max a toon out and unlock progression on gear, that for the fellow toons in the “posse” either also becom unlocked or at least get a bonus to how fast they can progress in the grind. One alternative is that maybe every toon you progress further decreases the grind for the next toon?
This kind of solidifies the way I think of my alts, I always see them as a group working together.
